If your existing well is slowing down, running low, or sputtering, you usually have four real choices: lower the pump, acidize the well to restore lost flow, deepen the existing borehole, or drill a new well. The right call depends on how your current well was built, what the rock looks like below your present depth, and how far the water table has dropped during the drought. Here is how we think through it, honestly, before recommending the most expensive route.
Start by confirming it is the water, not the equipment
A failing pump, a bad pressure switch, or a waterlogged tank can mimic a low well exactly. So before you weigh drilling decisions, rule out the cheap stuff. If the equipment checks out and the water level itself has dropped below your pump, then you are in genuine well-supply territory and the options below apply. Our overview of what to do when a well runs low walks through that first diagnosis in more detail.

Option 1: Lower the pump
This is the first thing we check and the least invasive fix. If there is still a healthy column of water standing in the well below where your pump currently sits, simply resetting the pump deeper can put you back in business. It only works when the borehole has usable depth left below the pump, and when the casing and the well construction allow the pump to be safely lowered. When it fits, it is by far the simplest answer. Our pump installation and service page covers how we set pumps for the long haul.
Option 2: Acidize to restore lost flow
Not every low well is short on water. Sometimes the well still sits in good water, but years of mineral buildup have plugged the fractures and screen that feed the borehole. In the limestone country out here, calcium scale and iron deposits slowly choke a well's intake, and the yield falls off even though the aquifer has not. A measured acid treatment can dissolve that buildup and bring the flow back. If your well has gradually weakened over time rather than dropping suddenly in a dry spell, well acidizing is often the smartest first move, and it costs a fraction of a new well.
Option 3: Deepen the existing well
Drilling the same hole deeper can reach a more dependable water level, but it is not always possible or wise, and that surprises people. Whether deepening makes sense comes down to how the original well was built:
- Casing diameter and condition. An older well with narrow, corroded, or collapsing casing may not safely accept a deeper bore or a modern pump. If the casing is compromised, you are often better off starting fresh.
- What the rock looks like below you. Deepening only helps if there is more water-bearing formation underneath your current bottom. In some spots you would just be drilling into dry or tight rock with no payoff.
- How the well was completed. The original construction method, the seal, and the borehole condition all decide whether the existing hole can be reworked at all.
When the construction cooperates and the geology below is promising, deepening can be a sound middle path. When it does not, pushing a tired old well deeper can throw good money after bad.
Option 4: Drill a new well
A new well is the last resort, but sometimes it is the right long-term answer, especially when a well is simply at the end of its service life or was poorly sited to begin with. A new well lets us choose the best location, set proper casing, and complete it to reach a more reliable zone. It is the most expensive route, which is exactly why we never recommend it until the cheaper options have been ruled out. When it is the right call, our water well drilling page explains how we plan and complete a new well in Hill Country rock.
How the drought changes the math
The Trinity Aquifer that underlies much of the central Hill Country draws down hard in dry years, and that drawdown is what pushes many otherwise-healthy wells below their pumps. A well that was perfectly adequate ten years ago can come up short simply because the regional water level has fallen. We keep an eye on Trinity Aquifer water levels and the local drought stages and restrictions because they shape what a reliable depth looks like today. In a deep drought, lowering a pump may only buy you a season, while deepening or a new, properly sited well delivers years of dependable supply. Long-term reliability, not just the cheapest fix this month, is the right lens.
How we help you decide
We start by measuring your well's depth, casing, and current water level, then read the geology and the drought picture together before recommending anything. The goal is always the least expensive option that genuinely solves the problem and holds up over the next several dry years, not the biggest invoice. If cost is a concern, we will talk through financing rather than steer you toward a quick fix that will not last. Tell us what your well is doing and we will take an honest look and lay out your real choices.
